About Tracking Program

Environmental Public Health Tracking

Before the Tracking Network, there was no single source where communities could access data and information to help them better understand relationships between the environment and health.

Environmental public health tracking is a type of surveillance. Surveillance is a method to monitor trends by collecting, interpreting, and reporting data. CDC's Environmental Public Health Tracking Network (Tracking Network) brings together health and environment data in one place, making it easier to compare hazards and exposures with health outcomes at a local and national level. The goal of the Tracking Network is to provide information to help improve where we live, work, and play.

The Tracking Network is part of CDC's National Environmental Public Health Tracking Program. The Tracking Program includes not only the Tracking Network but the people, resources, and program management involved in building this network. Learn more about the Tracking Program.

CDC provides funds to 26 state and local health departments to develop local tracking programs. Grantees submit data to the National Tracking Network and host their own data and information on their own websites. Some tracking grantees have data on environmental health topics not found on CDC's Tracking Network. Example topics include blue-green algae, Lyme disease, private well water, and radon.

Because of the Tracking Program, public health leaders and communities can make informed decisions about planning, implementing, and evaluating public health activities.

Health and environmental experts from states, cities, and other agencies helped CDC develop the indicators and measures you will find on this site. Tracking Network data were selected based on many factors including availability; quality; potential to help address information gaps; and priority for CDC and state and local health departments.

Tracking Environmental Health Data for Public Health Decision Making
Watch this CDC Public Health Grand Rounds presentation to learn how the Tracking Program is addressing the lack of environmental health data and how the program has informed public health decision making and action at the state and local levels.
